A comminution machine for waste includes a rotor that carries blade elements and cooperates with counter-blades, which are fixed to the housing. The rotor is driven by a synchronous motor that is excited by a controllable frequency converter. In order to keep the connected power of the comminution machine small and nevertheless be able to apply a large torque to the rotor, the synchronous motor acts upon the rotor via a reduction gearing and a clutch.
